While it has never been recognised by the state or commonwealth governments, the Principality of Hutt River received a letter from Queen Elizabeth II in 2016 on its 46th anniversary.

The tourist attraction even has its own postage stamps and currency, about 10,000 non-resident citizens and a treaty with indigenous land owners. But the “royal” family was hit with a $3 million tax bill in 2017, with Prince Leonard ordered to pay $2.7 million and his son Arthur to pay more than $240,000.
